I suppose we still haven't actually answered the original
question, as to why it would abort with:
"Unable to find device node for /dev/ad4s2b in /dev!"

The only thing I can think of is that sysinstall was
expecting a swap partition and wasn't given one,
although that sysinstall should be so brittle does not
agree with my general experience.

If the space to be installed in is greater than 6G
(or so) the defaults should work without a problem,
so assuming the defaults were used it should see
a /dev/ad4s2b as swap.  Of course we haven't asked
which version of FreeBSD or if there might be some
sort of buggish controller.
